8 Nov 2016 | | Abstract: | We report a significant change in friction of a $
m La_{0.55}Ca_{0.45}MnO_3$
thin film measured as a function of the materials resistive state under
ultrahigh vacuum conditions at room temperature by friction force microscopy.
While friction is high in the insulating state, it clearly changes to lower
values if the probed local region is switched to the conducting state via
nanoscale resistance switching. Thus we demonstrate active control of friction
without having to change the temperature or pressure. Upon switching back to an
insulating state the friction increases again. The results are discussed in the
framework of electronic friction effects and electrostatic interactions. | | Source: | arXiv, 1611.2684 | | Services: | Forum | Review | PDF | Favorites | |
